Check out this new article from the Daily Illuminator that Steve Jackson Games posted:

June 21, 2010: The Multiverse Is Really Big (http://www.sjgames.com/ill/archives.html?m=June&y=2010&d=21)

Apologies to Douglas Adams (http://www.quotationspage.com/quote/33085.html), but multiverse is really big. See, there's this whole universe of "big," but then there's an infinite amount of "big." It nearly hurts your head, thinking about it.</p>

Luckily, guides are available. Aside from GURPS Infinite Worlds (http://www.sjgames.com/gurps/books/infiniteworlds/), Phil Masters has provided us with Britannica-6 (http://www.sjgames.com/gurps/books/britannica-6/), an alternate Earth described in 70 pages. (Of course, Alternate Earths 1 (http://www.sjgames.com/gurps/books/altearths/) and Alternate Earths 2 (http://www.sjgames.com/gurps/books/altearths2/) contain many more worlds, though the page count allotted to each is a bit smaller.) We also have Collegio Januari (http://www.sjgames.com/gurps/books/collegiojanuari/), Lost Worlds (http://www.sjgames.com/gurps/books/lostworlds/), and I.S.T. (http://e23.sjgames.com/item.html?id=SJG30-1672) -- an organization of world-jumping wizards, a collection of timelines that "fell out" of Infinite Worlds, and a world of supers, respectively.</p>

And now there's Pyramid #3/20: Infinite Worlds (http://e23.sjgames.com/item.html?id=SJG37-2620). Looking for new worlds to visit? Here are three: a Roman interplanetary empire; a near-future with Soviet-dominated orbit; and a world where the creator took gritty cyberpunk, added anime, and stirred vigorously! Looking for new Hellworlds to dump the bod . . . er, research? Stephen Dedman has thoughtfully provided four, each nastier than the last. Plus, Jason "PK" Levine (author of Psionic Powers (http://www.sjgames.com/gurps/books/psionicpowers/)) presents a slew of new psionic abilities for worldjumpers and teleporters.</p>

Pyramid #3/20: Infinite Worlds also contains all those sorts of things Pyramid is known for . . . Murphy's Rules, Random Thought Table, and other odds and ends. Grab it now, while it's still in phase with this timeline!</p>
